Remote control system and method for a television receiver
First Claim
1. A system for controlling the movement of a cursor on a monitor screen, comprising:
- at least one remote control unit for remotely controlling the moving direction of said cursor on said monitor screen;
at least one light emitting element for emitting light indicative of a signal generated by a first click operation of said remote control unit;
a light detector for extracting a movement of the light transmitted sequentially from said remote control unit; and
, a control unit adapted to display the moving position of said cursor on said monitor screen corresponding to the extracted movement of the light from said remote control unit and to stop the moving position of said cursor if the movement of the light transmitted from said remote control unit changes in the opposite direction.

Abstract
A system and method for controlling the movement of a cursor on a monitor screen are provided. The system comprising at least one remote control unit having a plurality of push buttons for remotely controlling the moving direction of the cursor on the monitor screen; at least one light emitting element for emitting light that indicates a signal generated by the remote control unit; a light detector for extracting the light movement that is transmitted sequentially from the remote control unit; and, a control unit for displaying the moving position of the cursor on the monitor screen corresponding to the extracted movement of the light from the remote control unit, and also adapted to stop the moving position of the cursor upon releasing the push button of the remote control unit. The movement of the cursor on the monitor screen also can be stopped if the light movement transmitted from the remote control unit changes in the opposite direction.

12. A system for controlling the movement of a cursor on a monitor screen, comprising:
-
two or more remote control units, each having at least one light emitting element adapted to transmit light at different frequencies;
at least one light detector for detecting the light movement transmitted from each light emitting element of said remote control units; and
,a control unit for displaying said cursor on said monitor screen through a first click operation of said remote control unit and for translating the movement of said cursor based on the detected light movement from said remote control unit, wherein the motion of said cursor is halted if the movement of the light transmitted from said remote control unit changes in the opposite direction. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A method for controlling the movement of a cursor on a monitor screen through a remote control unit having at least one light emitting element, the method comprising the steps of:
-
pointing said light emitting element of said remote control unit toward the monitor screen;
transmitting a first light signal indicating the beginning of the movement of said cursor through a first click operation;
detecting the movement of light generated in response to said first click operation in at least two dimensions;
moving said cursor on said monitor screen corresponding to the detected light movement from said remote control unit; and
,stopping the movement of said cursor if the movement of the light transmitted from said remote control unit chances in the opposite direction. - View Dependent Claims (24, 25, 26)
